Tom let me know that UberTwitter has updated their Twitter app for BlackBerry to version 0.993 Release 2. This update to the original Beta-9 version just brings a few fixes and features that people wanted including improving battery usage. You can see exactly what was added in Release 2 below:

User action to retrieve a map You now have to click the ‘Retrieve Map’ button after opening a tweet in order for the map to be retrieved. This will result in substantially lower bandwidth requirements and improved battery life.

Resetting tweets to retrieve bug Fixed bug where on an upgrade the number of tweets to retrieve would reset to 60.

Highlight color in Midnight Theme bubble layout The highlight color in the Midnight theme when using the bubble layout is now much easier to discern.

Text Ad color We changed the color of the text ads to conform to the them colors. The ads are still clearly marked as an advertisement.

GPS Radio Activation The GPS radio will now only be activated when you open the compose tweet screen IF you have selected to use the GPS radio to determine location. This should greatly reduce battery drain, but may result in the location mechanism falling back to the cell tower method on some occasions.
